This Number 01457628195 (silent call) company has called numerous time over the past few days, I have reported this to Ofcom
I believe this is a company trying to sell something to stop nuisance calls!!

Received similar call identifying with Telephone 'preference'/or was it 'prevention'( the Asian accent was barely decipherable). This was from Tel No; 01457-628195 which had called 4-times previously in the preceding 3hrs, and several more times
